OIL-FEEDER.

SPECIFICATION forming part of Letters Patent No. 379,733, dated March 20, 1888.

Application tlledNovcniherl,1886. Renewed December 6, 1887. Serial No. 257,103.

To all whom, t may concern/f Be it known that I, NICHOLAS SEIBERT, a citizen of the United States, residing at Bos ton, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Oil-Feeders for Steam- Valves, (which is an improvement upon my application for Letters Patent for Oil-Feeders filed October 7, 1886, Serial No. 2l5,56l,) of which the following is a specification.

My invention relates to that class of oilfeeders commonly called displacement lubricators,77 wherein the water of condensation is fed into the oil contained in a reservoir and by its own gravity sinks to the bottom, displacing an equal amount of oil.

I disclaim constructions wherein are used a column of water or hydrostatic pressure.

Heretofore it has been very difficult to oil uniformly the valves and pistons of locomotivecylinders, for the reason that when the steam was shut oft' from the cylinders the oil was sucked out of the oil-feeders by the suction of the engines.

My invention is designed to overcome this difficulty.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure l represents a Vertical section through the oil-feeder; Fig. 2, a front view. Fig. 8 is an enlarged detail View of the valve G' and its seats.

In the said drawings, I represents a reservoir for containing the lubricating material, and A is a steam -pipe passing preferably through said reservoir, and communicating at its lower end with a steam-pipe, P, leading from the boiler. The upper end of the pipe A communicates with a chamber or condenser, C, on the top ofthe reservoir and surrounding the filling-plug B.

From this description it is evident that the steam entering the chamber is condensed, the water of condensation passing from the said chamber or condenser through the waterpas sage H and into the oil-reservoir, and by its own gravity sinks to the bottom, displacing an equal amount of oil. An oil-passage, K, communicatcs with the oil-tube J in the reservoir, and conveys the displaced oil to the steam-chamber O, from whence it is discharged upon the valves (No model.)

and pistons of the locomotive, as I shall hereinafter set forth.

F represents a valve located, preferably, bc neath the lower end of the oil-tube J, and having a check-valve, G, a similar valve, G', being placed in the discharge end of the condenser, thcse valves being designed to prevent the oil from being sucked out of the reservoir by the suction of the engines when the steam is shut off from said reservoir. By thus controlling the feed of oil, it is manifest that a uniform lubricating ofthe valves and pistons of the locomotive is obtained. A valve, M, closes the entrance ot' the steam-pipe P to the steamchamber O, and when opened the iniiowing steam not only rises through pipe A to the condenser, but also mingles with the oil as it passes `from the passage K, and is forced through oil and steam pipe N, leading to the steam chest or valve.

L represents a valve for controlling the passage ot' steam and oil through pipe N, and D represents the usual sight-feed, the reservoir being also provided with thc usual valve, E, for drawing off the contents of the reservoir.

My oilers are placed one on each side ofthe steam-gage in the cab,where the light used for the steam -gage may be directed upon each sight-feed ofthe oilers at night.

The operation of my invention is as follows: Plug B is removed and reservoir I filled with lubricant. Steam is let-on at M, which condenses in O, the water passing through H into the oil-reservoir, displacing the oil. The feedvalve F is now opened to give the required amount of oil. I then open valve L a very little to carry off the oil through pipe N upon the valvesvand pistons.

What I claim isl. The combination, with the oil-reservoir having an oil and water passage, respectively, and a condenser communicating with the water-passage, of au upwardly -moving checkvalve within the waterpassage and a horizontally-moving valve within the oil-passage for checking the feed of oil when the steam is shut oft', substantially as herein described.
